Описание: Abstract: The purpose of this research project was to evaluate techniques to improve the application of in situ penetration testing to Florida soils, with emphasis on the electronic cone penetrometer test (ECPT). Topics addressed included describing the spatial variability of soil properties, classifying Florida soils with the ECPT, and correlating the ECPT with the standard penetration test (SPT). A collateral purpose was to create an in situ test data base consisting of 97 ECPT soundings and 79 SPT tests. This data base was subsequently evaluated using statistical analysis. The spatial variability study was carried out to evaluate methods of interpolation between test soundings. The techniques studied included three deterministic approaches (the mean, median, and a 10% trimmed average), three distance-weighting methods (two based on reciprocal distances, and linear interpolation), a random field model (a hybrid distance-weighting/regression model), and regression analysis. While none of the approaches stood out as consistently superior predictors, the deterministic approaches were generally inferior to the other, more sophisticated methods. The distance-weighting methods and the random field model performed comparably, but were sensitive to individual test soundings. The regression models predicted slightly better on the average, and with more stability. The ECPT classification study used parametric and nonparametric discriminant analysis of cone data on soils that had been identified from the SPT test. The ECPT was able to group soil accurately into one of seven categories (organics, clay, silt, clayey sand, silty sand, sand, weathered rock) approximately 40% of the time. This percentage increased to 70% when the three sand categories were combined, reflecting the SPT drillers' difficulties in discriminating silty soils. In the SPT-ECPT correlation study, average q /N ratios for Florida soils were much higher than expected, possibly due to cementation or liquefaction. Regression analysis of the data suggested that the nature of the SPT-ECPT relationship is more a function of the magnitude of the tip resistance, and less of the actual soil type.

Ultrasonic Nondestructive Testing of Materials: Theoretical Foundations explores the mathematical foundations and emerging applications of this testing process, which is based on elastic wave propagation in isotropic and anisotropic solids. In covering ultrasonic nondestructive testing methods, the book emphasizes the engineering point of view, yet it relies on the physics and mathematics aspects involved in elastic wave propagation theory.
As a result, this resource becomes a missing link in the literature by combining coverage of the theoretical aspects of testing and providing intuitive assessments of numerous standard problems to illustrate fundamental assertions. Content includes a brief description of the theory of acoustic and electromagnetic fields to underline the similarities and differences as compared to elastodynamics. It also covers vector algebra and analysis, elastic plane and Rayleigh surface waves, and ultrasonic beams, as well as transducer radiation, inverse scattering, and ultrasonic nondestructive imaging.
Includes numerical computations to explain wave propagation phenomena and compare results of analytical formulations
Although ultrasonic nondestructive testing can often be roughly understood in terms of plane waves and beams, this book addresses the key issues of transducer radiation and defect scattering and imaging, respectively. The authors physically formulate point source synthesis, and, in mathematical terms, they use representation integrals with Green functions, always including intuitive interpretations with mathematical evaluations.
Replacing cumbersome index notation with a coordinate-free version, this reference offers step-by-step documentation of relevant tensorial elastodynamic cases involving isotropic and anisotropic materials. It provides all necessary mathematical tools readers require to understand the mathematical and physical basis for ultrasonic nondestructive testing.
Описание: This is a book about the invention and testing of ideas. By describing how to generate engaging problem situations for engineering students to solve it inspires original currents of thought.Make-and-test (MaT) is a practical way of testing ideas that challenges the validity of the ideas themselves and the manufacturing skills of the participants. Much of the project work described makes use of such simple materials as balsa wood and candle wax with the occasional appearance of the more exotic: fibre-glass-epoxy composites, for example; the properties and uses of these are examined in depth. All of the inventions described are intended to be well within the range of ingenuity and skills of first- and second-year engineering undergraduates. They can also be useful in stimulating the problem-solving skills of professional engineering and architectural designers so that everyday design questions and more one-off and personal undertakings such as the periodic design challenges offered by professional engineering societies can be interpreted more creatively. The major part of the book is devoted to case examples based on the author’s twenty-five years of experience in supervising MaT work but there are many opportunities and exercises throughout the text to explore new MaT projects.In essence, Make and Test Projects in Engineering Design encapsulates the experience of engineering design from the uncertainty of "Can I tackle this problem?" to the joyous "Aha!" when a solution is discovered. An invaluable teaching tool and resource for the engineering educator and all those planning and conducting make and test projects, this is the first book that formalises an important aspect of early learning in engineering design.
